Exact make, model and year evidence from official US sources. Recall campaigns, ODI investigations, complaint allegations and EPA estimates remain separate.
A campaign may cover only certain production dates, plants or equipment. A zero result here is not safety clearance. Use NHTSA’s official VIN tool for the individual vehicle.
Exact model-level NHTSA results for 1994 BUICK Century. Campaign records are official safety actions; applicability to a particular car still requires its VIN.
IN THE EVENT OF A PRIMARY ACCELERATOR CONTROL SPRING FAILURE, THE SECONDARY (BACK-UP) ACCELERATOR CONTROL RETURN SPRING WILL NOT RETURN THE THROTTLE TO THE FULLY CLOSED POSITION, AS REQUIRED BY FMVSS NO. 124, "ACCELERATOR CONTROL SYSTEM."
Consequence
CONSEQUENCE OF NON-COMPLIANCE: LOSS OF THROTTLE CONTROL COULD RESULT IN A VEHICLE CRASH WITHOUT PRIOR WARNING.
Remedy
DEALERS WILL REPLACE THE SECONDARY THROTTLE RETURN SPRING.
DURING ASSEMBLY, WATER MAY HAVE ENTERED THE ACCELERATOR CONTROL CABLE CONDUIT CAUSING IT TO DEVELOP A HIGH EFFORT AND/OR BINDING CONDITION IN VERY COLD WEATHER.
Consequence
HIGH EFFORT OR BINDING CONDITIONS CAUSE LOSS OF NORMALTHROTTLE CONTROL OR THE THROTTLE MAY NOT RETURN TO IDLE WHEN THE ACCELERATOR PEDAL IS RELEASED. IF THIS WERE TO OCCUR WHILE THE VEHICLE IS IN MOTION, A VEHICLE CRASH COULD OCCUR.
Remedy
THE DEALER WILL PURGE THE THROTTLE CABLE OF ANY INTERNALLY TRAPPED WATER, IF IT IS PRESENT.
THE RIGHT HAND SPINDLE NUT WAS NOT PROPERLY TIGHTENED DURING ASSEMBLY. THIS CAN CAUSE PREMATURE WHEEL BEARING FAILURE AND OVER TIME, THE SPINDLE CAN FRACTURE.
Consequence
THIS WOULD CAUSE THE WHEEL TO SEPARATE FROM THE AXLE AND RESULT IN A VEHICLE CRASH.
Remedy
DEALERS WILL INSPECT THE TORQUE ON THE RIGHT HAND FRONT SPINDLE NUT. IF THE SPINDLE NUT IS UNDERTORQUED THE DEALER WILL REPLACE THE RIGHT HAND FRONT WHEEL BEARING ASSEMBLY AND THE SPINDLE NUT WILL BE REPLACED.
WATER INTRUSION CAN CAUSE A SHORT CIRCUIT IN THE POWER DOOR LOCK ASSEMBLY.
Consequence
A SHORT CIRCUIT IN THE POWER DOOR LOCK ASSEMBLY CAN RESULT IN A VEHICLE FIRE.
Remedy
DEALERS WILL REPLACE THE POWER DOOR LOCK RELAY AND ANY CORRODED TERMINALS. IN ADDITION, THE NEW RELAY WILL BE RELOCATED TO AN AREA WHERE WATER INTRUSION IS LESS LIKELY.
THE CRUISE CONTROL CABLE MAY SEPARATE FROM THE CONDUIT END FITTING WHILE ENGAGED AND ACCELERATOR CONTROL COULD BE LOST.
Consequence
LOSS OF ACCELERATOR CONTROL MAY NOT REDUCE ENGINE SPEEDTO A LEVEL ANTICIPATED BY THE DRIVER. ALTHOUGH THE VEHICLE CAN STILL BE STOPPEDWITH THE SERVICE BRAKE, LOSS OF ACCELERATOR CONTROL COULD RESULT IN A VEHICLECRASH WITHOUT PRIOR WARNING.
THESE VEHICLES WERE ASSEMBLED WITH REAR OUTBOARD SAFETY BELT ANCHORAGES THAT MAY NOT WITHSTAND THE REQUIRED LOAD. THIS DOES NOT COMPLY WITH FMVSS NO.210, "SEAT BELT ASSEMBLY ANCHORAGES."
Consequence
CONSEQUENCE OF NON-COMPLIANCE: IN A COLLISON, STRESS CAN CAUSE THE ATTACHMENT METAL TO TEAR AND ALLOW THE ANCHORAGE TO SEPARATE FROM THE BODY OF THE VEHICLE. THE SAFETY BELT MAY NOT PROTECT AN OCCUPANT IN THE EVENT OF A VEHICLE CRASH.
Remedy
DEALERS WILL REPLACE THE EXISTING ANCHOR BOLTS WITH A NEW SHOULDER BOLT AND THREAD LOCKING ADHESIVE. ADDITIONALLY, NOISE CONTROL PATCHES WILL BE APPLIED AT EACH ANCHORAGE.

Complaints across nearby Buick Century model years
Totals for the same nameplate, scaled against its highest year here. They are not adjusted for how many were sold, how old they are, how far they are driven, or how much publicity a fault received — an older or better-selling year will usually carry more reports. This shows where the reporting sits, not which year is better.
An investigation means ODI reviewed a possible safety issue for this exact model-year identity. Opening one is not a defect finding; closing one does not by itself clear a vehicle.
VERIFIED EMPTY IMPORT SNAPSHOT
No exact NHTSA ODI investigation row was matched.
The checked bulk snapshot returned zero investigation action numbers for 1994 BUICK Century. That is source coverage, not proof that no issue exists or will be investigated later.

The canonical URL is this file’s permanent public identifier. Source IDs and timestamps show exactly what was matched and when; they do not turn the evidence into a verdict.
Only NHTSA vPIC, NHTSA ODI complaints and investigations, NHTSA recalls and FuelEconomy.gov contribute to this vehicle claim. CPSC equipment notices are searched separately and never joined to vehicle fitment. UK MOT, Canadian, New Zealand and European records are not merged into this US claim.
